single output & wide adjust output
These ruggedly-built power supplies have tightly
regulated outputs and low output ripple. Features include
status indicator lights, overvoltage protection, EMI
SPECIFICATIONS
Input Voltage: 90-132 VAC, 49-61 Hz, single phase.
For models W24GT50, W28GT42 and W48GT25, the
use of a 30A line is recommended and when operating
on 50 Hz input, derate output by 5%.
Startup Time: 400 mS maximum (250 mS typical).
Input Undervoltage: An input of less than 90 VAC (180
VAC with “–230” option) will not damage power supply.
Regulation:
Remote Voltage Programming: The output voltage may
be controlled by means of an external potentiometer
(2500 ohms for single output models; 50,000 ohms for
wide adjust output models).
Polarity: Output is floating and may be used in either
polarity.
Drift: ±0.1% maximum over 8 hours, after 30 minute
warmup.
Temperature Coefficient: ±0.02%/°C (Typical).
Holdup Time: 33 mS minimum (At nominal input voltage,
with full load).
Transient Response: 300 µS to return to ±1% of output
setting. Maximum of ±3% output excursion following a
load step change from 50% to 100%.
Remote Sensing: Compensates up to 0.5 volt drop per
output line, within the limits of the output voltage
adjustment range.
Overload/Short Circuit Protection: Foldback current
limiting with automatic recovery.

filtering, ‘soft start’ operation and provision for external
output inhibiting (TTL-compatible).
Overvoltage Protection: Latches power supply OFF,
reset by momentarily removing AC input power. Red
indicator lights to indicate latchup.
Output Inhibit: Applying between +2 and +30 Vdc to the
inhibit terminal will disable the supply (T TL compatible).
Thermal Protection: Thermostat, self-resetting.
Efficiency: See table. (Typical, at nominal input voltage,
with full load.)
Ambient Operating Temperature: 0 to +71°C.
Storage Temperature: – 40 to +85°C.
Cooling: Forced-air cooled (ball bearing fan); air enters
back of power supply and exits from front.
Switching Frequency: 55 kHz (Typical).
Isolation:
Mounting: Threaded mounting holes permit mounting to
a chassis, cabinet wall or bracket, or they may be used
on a test bench or tabletop. To mount from the power
supply side of the mounting surface or for DIN rail
mounting, see accessory Mounting Kits on page 37.
OPTIONS
230 Volt Input: For applications where operation on an
input of 180-264 VAC, 49-61 Hz, is desired. To order, add
suffix “–230” to the model number and $40.00 to the
standard price.The “–230” option requires two additional
days.
Input to output: 1400 Vdc
Input to case: 1400 Vdc
Output to case: 400 Vdc
